Why would you want to pva new block work?

 

[frankk]

To give it a bond,make it stick..is there no need?

Just use neat pva and stick your pebbles to that or have a good curry and aim and fire job done lol

No need for it on new block work. Aslong as the joints have been raked out that will provide a good enough key for your scratch coat

Couple of nails in yer base coat frank.300mm centres will do

On new block work I'd say a light wet down first before your scratch coat. Never heard of external pva?? I'd only use SBR on exterior work but defo not on new block work unless it's those awful thermalites then I'd micro them

Even normal blocks. The key is good enough without scud, just keep the fist coat soft enough that it goes into the holes of the blockwork.
I don't scud when I don't have to.

Have you ever tried hacking sand and cement render off a block? No need the key is there just get the gear soft like what's been said but add a water proofer to control the suction for your top coat.

This time of year and near Christmas I normally just add 2 mince pies to every bucket of water per mix , and nats cock of double cream just to make things go smoothly. Make sure you use Mr Kiplings otherwise it doesn't work.
